To talk about the excellent anti-tank rifles of the Second World War, many people would say that Germany's Mauser M1918 anti-tank rifle, but another small country produced a anti-tank rifle also has a big bright spot let
Germany and other countries very admire, so far a mention of tungsten alloy bullets always mention this country, it is Poland!For a long time, countries produced bullet materials are mainly brass, a small number
of lead and steel, because the brass plasticity. In the early years, it was a brass bullet against human beings, helpless in the face of a heavy armored tank.In order to penetrate steel armour, many people's approach
is to increase the firepower of guns, so that the bullet has a very high rate of fire, good penetration of steel armour, but the Polish gun designer's approach is not the same, they think, to wear steel armour, first from the bullets, so the industry's common
tungsten alloy technology applied to bullets, It also produced a new anti-tank rifle: 7.92mm M35 Maroskozek anti-tank rifle.M35 rifle is not a bright spot, it is based on Mauser M1918 anti-tank rifle based on the
design, is to remove the M1918 anti-tank rifle unnecessary structure, making the gun the world's smallest quality anti-tank. The biggest bright spot of the gun was the use of tungsten alloy bullets, this is at that time the world did not think of things, tungsten
alloy than steel density is still hard, wear steel that is due, but tungsten alloy bullet tough features also on the M35 anti-tank rifle damage to the rifling is very large, hit 200 hair on the scrap.To solve this
problem, tungsten alloy bullets are wrapped in copper-nickel, which looks like silver, so Japan calls it a silver bullet. Tungsten Alloy green bullets, also known as green Bullets, because the production of tungsten alloy bullets relative to lead bullets to
environmental protection, so there is a green bullet laudatory name.

Tungsten-core for armor-piercing is one of the most popular weapon types in modern military weapons. The internal loading of tungsten alloy shells is called tungsten core armor-piercing rounds.

The main targets of the tungsten-piercing rounds are tank armor and rugged fortifications, because the tungsten core armor-piercing rounds are tough enough to compete head-on with these hard things.

The tungsten
core armour-piercing is composed of a hood, a projectile core, a projectile body and a traction light tube. The core is also the main part of the armor-piercing projectile, which is made of high density (17~18 g/cm3) tungsten alloy. Tungsten alloy is a kind
of dense metal not only large density and extraordinary hardness, is the main material for the manufacture of hard core munitions. The projectile body is made of low carbon steel or aluminum alloy, which mainly plays the role of supporting core, and has a
guide band which can guarantee the rotation stability of projectile. The core is fixed in the middle of the projectile, and when the armor is hit, the projectile is cracked and the core is pierced.The core diameter is small, only the 1/3~1/2 of artillery
caliber, the target kinetic energy (ratio of projectile kinetic energy to the cross section area) is improved. The vertical piercing property is good, the tungsten alloy core is high hardness, has the characteristic of resisting the pressure not to pull, wear
a basic not to deform, penetrate armor to form fragment, increase the killing and burning effect.Tungsten core armor piercing projectile with high proportion of tungsten alloy manufacturing, the density can reach 18g / cm3, is 2.3 times the proportion
of steel (7.8g / cm3), so the heart of cross-section density is conducive to improving the speed of flight survivability and the steel Penetration ability to improve armor-piercing kinetic energy to armor a fatal blow.Tungsten alloy is also a high temperature,
good thermal stability of metal materials. Tungsten core in the penetration arm to withstand high pressure and high temperature environment, the use of tungsten alloy core, even in the high temperature and high pressure environment will not bond deformation.

12.7mm Tungsten Core Shelling, was introduced in 1975 from the United States Pacific Technology company is in the process of the development of the 0.5APDS bomb, is a second-caliber rotating and stable armor-piercing rounds. It has been proved
by experiments that the projectile has the advantages of high speed, low ballistic trajectory and strong armor-piercing. Among them, "armour-piercing power" is the most prominent advantage of the projectile compared with the same caliber projectile.

W95 type 12.7 mm Foreign trade heavy machine gun: W95 type machine gun is in China 85-type 12.7 mm gun as the blueprint developed. This machine gun has the powerful, the allotment tungsten core armor-piercing rounds, the barrel has 8 right spins and so on
the outstanding merit. The tungsten core armor-piercing projectile can penetrate the armor plate with a thickness of 15 mm at a distance of 1000 meters and a hit angle of 45 degrees. The guide is 380 mm, launches NATO O.5-inch series of large-caliber bullets,
the armor piercing ability outstanding. W95 Tripod is relatively stable, buffer device damping obvious, shooting gun body jitter small, to ensure good shooting accuracy and high shooting speed. In addition, through the use of armor-piercing, burning, drag
light, explosion and other combinations of warheads, to achieve multiple targets on the battlefield hit. The gun is equipped with an advanced white light sight and can also be used as a sniper rifle.

With rapid development of medical science, more and more tungsten
radiation shieldings are used in our lives. Medical instruments x-ray and nuclear power stations have become widespread and are now affecting all our lives. It is essential that people paid more attention to radiation and even more important for the institutions
to protect public from the radiation exposure and to make sure to protect every radiation source of X-ray radiation, gamma radiation (energetic electromagnetic radiation), radiation of alpha particles (helium atoms) beta particles (electrons) and cosmic radiation,
etc.

In
order to protect patients, doctors, nurses and other people who may be exposed to radiation, sources of the radiation must be safely separated and shielded. It is crucial that holding and delivery instruments for radioactive materials would keep the radiation
levels low enough, not to create harmful effects of ionizing radiation such as breast cancer, skin cancer, etc. Lead and steel are the traditional protection materials, but tungsten alloy radiation shielding is without a doubt the best solution. Excellent
radiation-absorption and radiation shielding, twice the density of lead and good physical resistance are main reasons to use tungsten alloy radiation shielding.

Advantage of Tungsten Alloy Radiation Shielding

Experts find that radiation exposure could be reduced by maxing shielding.The density oTungsten Alloy Radiation Shieldingf a material is related to its radiation
protection ability. Higher density means better stopping and absorbing radiation ray . Due to a higher density than most other materials, tungsten radiation shielding has a much higher ability of absorbing and stopping almost rays than others metals such as
the traditional radiation shielding - lead. Tungsten radiation shielding greater linear attenuation of gamma radiations means that less is required for equal shielding. Alternatively equal amounts of tungsten shielding provide diminished exposure risks than
equivalent lead

Tungsten
heavy alloy is the right material for radiation protection, as its combination of radiographic density (more than 60% denser than lead), machinability, good corrosion resistance, high radiation absorption (superior to lead and steel), simplified life cycle
and high strength. Tungsten radiation shielding can provide the same degree of protection as lead whilst significantly reducing the overall volume and thickness of shields and containers. Besides, compared with lead or depleted uranium (DU),tungsten radiation
shielding is more friendship for the environments both lead and DU for it is no any toxic.Applications of Tungsten Radiation Shielding
